Certainly, you can specify your own log format using something like

LogFormat "%V %b" parseable
CustomLog /var/log/httpd/domain.com-parseable_log parseable

You can add the new custom log type alongside the existing combined log
format.

That should give you a log with

	domain.com 324

or something of that ilk on each line as well as a timestamp prefix.
